Description

Technical Field

[0001] This utility model relates to the field of medical and nursing equipment technology, and in particular to a multi-directional translation device for a nursing bed. Background Technology

[0002] To meet the needs of diagnosis and treatment, prevent complications, and improve comfort and convenience of care, some patients need to be moved or turned over in bed. During examinations and surgeries, moving the patient can avoid improper handling that could lead to wound tearing, tube dislodgement, or increased pain. For example, patients undergoing spinal surgery need to keep their body axis aligned to prevent spinal displacement. For long-term bedridden patients, regular repositioning can prevent pressure sores, lung infections, and deep vein thrombosis.

[0003] When performing lateral or turning operations on patients, it is usually done by 2-3 nurses working together. They choose appropriate tools according to the patient's condition. In some cases, a movable sliding mat is used to assist the patient's lateral or turning operation. Although this can improve the efficiency of the operation, it also has certain limitations. First, when pulling the sliding mat manually, multiple people are needed to complete the lateral or turning operation for patients who are heavier or have limb movement impairments. This not only consumes the nurses' physical strength, but may also cause the patient's body to twist or bump due to improper coordination, or cause the nurses' back strain. Second, although the common sliding mat can reduce friction, it can only achieve movement in one direction and cannot meet the needs of lateral movement in the head / foot direction of the bed.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figures 1-6 As shown, this utility model provides a multi-directional translation device for a nursing bed, including a bed 1. A base frame 2 is fixedly installed at the bottom of the bed 1. Two hanging plates 3 are also fixedly installed on one side of the bottom of the bed 1. A bearing seat 15 is fixedly installed on the side of the base frame 2 opposite to the hanging plates 3. A main controller 4 is also fixedly installed on the base frame 2 below the bearing seat 15. A translation mechanism 5 is provided between the bed 1 and the base frame 2. The translation mechanism 5 includes multiple side beams 6 installed on both sides of the base frame 2. A folding guardrail 7 is movably installed between two side beams 6 on the same side. The two side beams 6 located between the base frame 2 and the folding guardrail 7 are also fixedly connected to a guide beam 8. Two support seats 9 are movably installed on the beam 8. A cloth roller 10 is set between the two support seats 9. A rotating shaft 11 is fixedly installed in the middle of the cloth roller 10. The two ends of the rotating shaft 11 are respectively rotatably installed in one of the support seats 9. A first motor 12 is also fixedly installed on one side of the two support seats 9. The first motor 12 is electrically connected to the main controller 4 through a cable. A first connecting beam 13 is fixedly connected between the two guide beams 8. One side of the first connecting beam 13 is also fixedly connected to two hanging plates 3. A second motor 14 is fixedly installed in the middle of the first connecting beam 13. The second motor 14 is also electrically connected to the main controller 4 through a cable.

[0026] like Figures 1-2 As shown, the main controller 4 is connected to a handheld remote control via a cable, which facilitates the start, stop and steering control of the first motor 12 and the second motor 14 by using the handheld remote control in conjunction with the main controller 4.

[0027] like Figures 1-6As shown, a mounting groove 16 is provided inside the guide beam 8, and a guide rail 17 is fixedly installed at the bottom of the mounting groove 16. The guide beam 8 provides a mounting base for multiple support seats 9, and the mounting groove 16 provides conditions for the sliding of the support seats 9 and reduces the sliding friction of the support seats 9. A sliding groove 18 is provided at the bottom of the support seat 9, and a slider 19 is fixedly installed at the top of the sliding groove 18. The bottom of the support seat 9 is slidably connected to the guide beam 8 through the sliding groove 18, and the slider 19 is slidably connected to the guide rail 17. The support seat 9, which can be horizontally slidably adjusted on the guide beam 8, can provide conditions for the patient to move towards the head of the bed. The outer side of the cloth roller 10 is coated with a friction layer, which can stably realize the reciprocating rotation of the cloth belt 25 between the two cloth rollers 10. Protective covers 20 are fixedly installed on one side of each of the two support seats 9. The protective covers 20 are also inserted through the outside of the first motor 12. A keyway 22 is provided at the output end of the first motor 12. The keyway 22 and the key shaft 21 are interlocked and connected. The output end of the first motor 12 is connected to the key shaft through the keyway 22. The two support seats 9 are interlocked, which allows the rotating shaft 11 to drive one of the cloth rollers 10 to rotate, thereby providing power for the cyclic rotation of the cloth belt 25. A second connecting beam 24 is fixedly connected between the two support seats 9. An internal threaded sleeve is fixedly installed in the middle of the second connecting beam 24. The cloth belt 25 is wrapped around the outside of one of the cloth rollers 10, and the other side of the cloth belt 25 is fixedly connected to the outside of the other cloth roller 10. The two cloth rollers 10 can realize the reciprocating movement of the cloth belt 25, which facilitates the patient's translation or turning over to one side of the bed 1. The output end of the second motor 14 is fixedly installed with a lead screw 23 through a coupling. The end of the lead screw 23 away from the second motor 14 is rotatably connected to the shaft seat 15, and the lead screw 23 is also fixedly connected to the internal threaded sleeve in the second connecting beam 24. The second motor 14 rotates the lead screw 23 in the internal threaded sleeve in the second connecting beam 24, which can cooperate with the two support seats 9 to realize the movement of the entire device towards the head or foot of the bed, thereby facilitating the patient's movement towards the head or foot of the bed.

[0028] It should be noted that this utility model is a multi-directional translation device for a nursing bed. Before use, it is necessary to confirm that all components of the device are securely connected, the main controller 4 communicates normally with the handheld remote control, the cloth belt 25 is undamaged, and the friction layer of the cloth roller 10 is intact.

[0029] When moving the patient to either side of the bed 1, the two first motors 12 can be turned on by hand-held remote control device in conjunction with the main controller 4. Then, the output ends of the two first motors 12 drive the rotating shaft 11 to rotate through the keyway 22 and the key shaft 21 insertion structure, which drives the two cloth rollers 10 to rotate synchronously, so that the cloth belt 25 moves back and forth between the support seats 9. Simultaneously, the operator can cooperate with a nurse to slightly lift the leg position and shoulder position of the rotating shaft 11, so that the traction force of the cloth belt 25 can move the patient to the left or right side of the bed 1.

[0030] To adjust the patient's position at the head or foot of the bed, the second motor 14 can be activated via a handheld remote control and the main controller 4. The second motor 14 drives the lead screw 23 to rotate via a coupling. The lead screw 23 engages with the internal threaded sleeve in the second connecting beam 24, causing the support seat 9 to slide along the path of the guide beam 8 and the guide rail 17. That is, the support seat 9 moves horizontally in the mounting groove 16 of the guide beam 8 through the sliding structure of the slide groove 18 and the slider 19. Simultaneously, the operator can work with a nurse to slightly lift the patient's legs and shoulders, thereby moving the cloth belt 25 and the patient towards the head or foot of the bed.

[0031] When turning a patient over, the first motor 12 is controlled to rotate at a low speed by a handheld remote control device, causing the cloth belt 25 to move slowly to one side. At this time, a single person can support the back or buttocks on the opposite side of the patient's body to ensure the stability of the body axis during the turning process. As the cloth belt 25 moves to one side, since one side of the patient's body is in contact with the cloth belt 25, the cloth belt 25 will gradually move the side of the patient in contact with the cloth belt 25 towards the operator, thus completing the turning operation.
